undorphins 

A negative feeling after a major workout, whether it is being tired, exhausted, depressed, etc. The opposite of endorphins.

After going for a run, I felt exhausted with pain coursing through my body, followed by feeling tired. Why did I have so many undorphins?

endorphins 

The body's natural opioids to make a person feel happy! Also to reduce pain. The only place these are found naturally is in the bloodstreams of people who are in love, in diet sodapop, & in chocolate!

I'm So Grateful for endorphins! & I love diet sodapop & chocolate & being in love!

Endorphins 

Your body's natural pain reliever, released when stress or pain levels are high, or after an orgasm.
Equivalent to a narcotic pain reliever once released.

I went for a run and got the Runner's High (endorphins), it felt great.
